When the bile within the gall bladder collects and settles it has the potential to form gallstones. Although most gallstones dissolve on their own without producing any symptoms, about 15 per cent of people with stones experience pain that, in some cases, requires surgical removal. A recent study confirms that exercise helps reduce the risk of developing gallstones. Regular activity may “shake up” the bile, preventing it from crystallizing into stones.

The study took into account exercise habits, obesity, alcohol use, and reproductive history. Compared to a sedentary lifestyle, those who were active decreased their risk of gallstone formation by about 60 per cent
